Z.Z. and W.M. analyzed the genes related to fiber development and abiotic stresses.
"Nowadays, I spend as much time studying where the business is going as I do with the science," said Dr. Michael B. Cain, Corning's manager for fiber development.
In the resulting allotetraploid the At subgenome provides most of the genes for fiber development.
A total of 535 cotton fiber development genes, including 103 fiber transcription factors, 259 fiber development genes, and 173 SSR-contained fiber ESTs, were analyzed at the subgenome level.
In the present study, the organization and evolution of the fiber development genes were investigated through the construction of an integrated genetic and physical map of fiber development genes whose functions have been verified and confirmed.
There is more fiber development gene information accumulated from the four fiber development stages, fiber initiation, elongation, second wall deposition, and maturation than from the study of transcription factors.
The sequence collection reflected the research focuses in that 432 of the 535 80.7%) collected sequences are fiber development genes.
Among them, 259 were fiber development genes, 103 were transcription factors, and 173 were genetically mapped SSR-contained fiber ESTs.
This study began with collecting sequences of cotton fiber development genes and transcription factors that were previously published.
In order to resolve these conflicts and to elucidate the distribution, organization, and network of genes for fiber development in tetraploid cottons, a total of 535 fiber-related genes of known function in fiber development, including both fiber development genes and transcription factors, were collected and anchored to integrated genetic and physical contig maps.
ROS have several roles in cotton fiber development.
